wherein the controller restricts a motion of the work unit in a first predetermined direction in the restriction process, and the first predetermined direction indicates a downward direction of an inclined surface where the main body is positioned, and
the main body supports the work unit and includes a swivel body supported by a traveling body in a swivelable manner, and the controller restricts a swivel motion of the swivel body in the first predetermined direction in the restriction process.
